Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101442, here are decompositions:
- 13 + 101429 = 101442
- 23 + 101419 = 101442
- 31 + 101411 = 101442
- 43 + 101399 = 101442
- 59 + 101383 = 101442
- 79 + 101363 = 101442
- 83 + 101359 = 101442
- 101 + 101341 = 101442
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 101,442 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
